Secondary O2 Sensor on OBD-2
 

Hey. Built a test pipe for my '00 Si and my secondary 02 sensor doesn't have a home now. Any ideas on how to keep my ECU from tripping code? Thanks for your help.

Some guys have ran a O2 emulator/simulator which basically tricks the ECU into thinking there is a perfectly fine O2 sensor attached.

just find a nut that fits the sensor, drill a hole in your test pipe and weld on the nut to it. then you will have a place for the sensor. i havn't tried this but this is what i am going to do when i make mine.

I wrapped mine in aluminum foil, and put it under the dash....works like a charm...no codes at all.

i got the simulator... 40 bucks no codes... 98Civic DX

Do you know the wrench size for the O2? I need to replace my but I need to buy a wrench. the adjustable wrench keeps sliping. Thanks.

they sell a socket to take the o2 sensor off its like 10 bucks

yes get the socket it is designed so that it will not mess up wires.. kinda hard to explain. looks like a real socket but cut open so the wires will not get in the way.. and get some good lubricant and breaker bar maybe to get the sucker out.. it can be a hassle

I'll try the foil/dash trick, see how that goes. Thanks.

same size as plug wrench

Can you shed some info on where to get the Simulator?

Never use penetrating oil on an O2 sensor you are planing to reuse, it will kill a good sensor in no time.

On a similar note....how much do these sensor usually cost. I went to Auto Zone and the guy told me 239.00 for one of these, i told him that him and his computer are crazy, this idiot didnt even know how to pronouce Acura he pronounced it
a-ku-ra!! anyways how much do they really run for???

Re: Secondary O2 Sensor on OBD-2 (shane Z)
 

where did you buy the o2 simulator.. i need one

Re: Secondary O2 Sensor on OBD-2 (JDM B Series)
 

I wouldn't do the foil thing. I think you have these 2 options - 1. get yourself either a jdm obd2 ecu or a obd1 ecu; both do not utilize the 2ndary o2 obviously...2. get yourself the emulator.

why, foil works fine.
